Jurnal Teknologi Kedirgantaraan (JTK) is committed to the long-term preservation, accessibility, integrity, and availability of its published scholarly content. Digital archiving procedures protect published articles and their metadata against data loss, technical failures, and disruptions to journal operations.

1. Digital Archiving and Preservation

All published articles are archived on the official journal website using the OJS platform.

Article preservation

Articles are kept in final published PDF format, organised by year, volume, and issue.

Metadata preservation

Titles, authors, abstracts, keywords, publication dates, and DOIs (where assigned) are kept in OJS.

XML archiving

Article and issue metadata may be exported as XML to support exchange, migration, and preservation.

Database and file backup

Copies of the OJS database and essential publication files support recovery and continuity.

Separate backup storage

Backups are stored securely, apart from the primary hosting, to reduce the risk of simultaneous loss.

2. Backup and Data Recovery

FrequencyBackups of the OJS database and essential publication files are made at least once a month and after each new issue is published.
StorageCopies are kept in secure institutional or cloud-based storage, with access restricted to authorised journal personnel.
VerificationThe editorial team and technical administrator periodically check that archived files are complete and accessible.
RecoveryAfter data loss, server failure, or website disruption, the journal will make reasonable efforts to restore content and metadata from backups.

3. Long-Term Accessibility

JTK maintains free and continuous access to its published content through the official website.

All published articles remain available in the online archive without subscription fees. The journal also keeps bibliographic metadata accurate and consistent to support identification, citation, and dissemination.

4. Migration or Discontinuation

System migration

During server migration, platform upgrades, or management changes, the journal will take reasonable measures to preserve and transfer articles, metadata, and archival records.

If publication ceases

The publisher and editorial team will make reasonable efforts to keep previous content accessible through institutional digital storage or another suitable archive, subject to resources and technical capability.

5. Archiving Responsibilities

The editorial team, with the publisher and technical administrator, implements and maintains the archiving procedures.

ContentManaging published content and maintaining backup records.
FilesVerifying archived files and coordinating data recovery.
PracticeReviewing how effective digital preservation practices are.

6. Policy Review and Improvement

This policy is reviewed periodically so that it stays relevant to the journal's publishing operations, technical infrastructure, and preservation requirements.

Planned improvement: JTK may adopt recognised third-party preservation services, such as the PKP Preservation Network (PKP PN), when technically and institutionally feasible.
